【摘要】：為在蘇南地區(qū)農(nóng)村推廣變量施肥技術(shù)提供一種可能的實(shí)施途徑,根據(jù)蘇南地區(qū)的農(nóng)業(yè)生產(chǎn)實(shí)踐經(jīng)驗(yàn),探討一種簡易的農(nóng)田施肥處方的獲取途徑,并結(jié)合百度地圖API構(gòu)建變量施肥電子處方圖系統(tǒng),對(duì)系統(tǒng)結(jié)構(gòu)和實(shí)現(xiàn)方法進(jìn)行了詳細(xì)介紹,重點(diǎn)討論農(nóng)田電子地圖的構(gòu)建與應(yīng)用普通精度GPS模塊實(shí)現(xiàn)田塊快速定位識(shí)別的方法。以江蘇省南京市雙魚龍莊13.3hm2試驗(yàn)田為測試對(duì)象,在Android設(shè)備上構(gòu)建相應(yīng)的電子處方圖系統(tǒng),并進(jìn)行基于自然田塊的定位識(shí)別性能測定試驗(yàn)和變量施肥試驗(yàn)。試驗(yàn)結(jié)果表明:系統(tǒng)測試數(shù)據(jù)穩(wěn)定,定位信息經(jīng)過卡爾曼濾波算法處理后,當(dāng)測試點(diǎn)距離農(nóng)田邊界2m時(shí),定位識(shí)別正確率達(dá)到86.8%,距離邊界2m時(shí),定位識(shí)別正確率達(dá)到100%。系統(tǒng)指導(dǎo)變量施肥機(jī)施肥,其實(shí)際播量相對(duì)誤差小于5.9%。說明本系統(tǒng)能夠有效識(shí)別作業(yè)位置,具備指導(dǎo)田間變量施肥的能力。具備在蘇南地區(qū)農(nóng)村推廣應(yīng)用的前景。
[Abstract]:In order to provide a possible way to popularize variable-rate fertilization technology in rural areas of southern Jiangsu province, a simple way to obtain fertilizer prescription for farmland is discussed according to the practical experience of agricultural production in southern Jiangsu province.Combined with Baidu map API to construct variable rate fertilization electronic prescription map system, the system structure and realization method are introduced in detail. The construction of farmland electronic map and the method of realizing field block fast location identification by using common precision GPS module are discussed emphatically.Taking Pisces Longzhuang 13.3hm2 experimental field in Nanjing, Jiangsu Province as the test object, the corresponding electronic prescription map system was constructed on Android equipment, and the performance measurement test and variable rate fertilization test based on natural field were carried out.The experimental results show that the system test data is stable and the location information is processed by Kalman filter algorithm. When the test point is 2 m from the farmland boundary, the accuracy rate of location recognition reaches 86.8%, and when the distance boundary is 2m m, the accuracy rate of location recognition reaches 100%.The relative error of sowing quantity is less than 5.9.It shows that the system can effectively identify the working position and has the ability to guide the field variable fertilization.It has the prospect of popularizing and applying in the rural areas of southern Jiangsu.
